Abstract
In some examples, a filtration assembly for hemodiafiltration therapy includes a filtration body connector configured to removably mechanically connect the filtration assembly and a dialyzer. In examples, the filtration assembly is configured to remain substantially stationary relative to the dialyzer when the filtration assembly mechanically mates with the dialyzer. The filtration body connector is configured to removably mechanically connect the filtration assembly with a plurality of different types of dialyzers, which may be selected based on a prescription for a particular patient.
Claims19
A medical system comprising:
- a filtration membrane including a first side and a second side;
- and
- a filtration body defining an interior volume between a proximal end and a distal end, wherein the filtration membrane is positioned within the interior volume, the filtration body comprising:
- a filtration proximal access at the proximal end configured to receive a blood flow, wherein the filtration proximal access is in fluid communication with the first side of the filtration membrane;
- a filtrate access in fluid communication with the second side of the filtration membrane;
- a filtration distal access at the distal end,
- wherein the filtration distal access is in fluid communication with the first side of the filtration membrane and the filtration proximal access, wherein the filtration distal access is configured to provide at least a portion of the blood flow to a dialyzer;
- and
- a filtration body connector secured to the distal end, wherein the filtration body connector is configured to removably mechanically mate with the dialyzer to enable the filtration distal access to provide the portion of the blood flow to the dialyzer when the filtration body connector mechanically mates with the dialyzer;
- and
- the dialyzer,
- wherein the dialyzer includes a dialyzer body,
- wherein the filtration body defines one of a protrusion or a recess and the dialyzer body defines the other of the protrusion or the recess,
- wherein the recess is configured to receive the protrusion,
- wherein the protrusion or the recess defined by the filtration body defines the filtration distal access and defines the filtration body connector,
- wherein the protrusion or the recess defined by the dialyzer body defines a dialyzer body connector, and
- wherein the dialyzer body connector is configured to removably mechanically mate with the filtration body connector to cause the filtration body connector to removably mechanically mate with the dialyzer.
